Population level trends help epidemiologists to monitor the incidence and prevalence of diseases over time. This information is essential for:
1. Public Health Planning: By examining trends, health authorities can allocate resources efficiently and develop targeted health policies. 2. Early Detection of Outbreaks: Trends can signal the emergence of new diseases or the resurgence of old ones, allowing for prompt intervention. 3. Evaluation of Interventions: Trends can show the effectiveness of public health interventions, such as vaccination programs or smoking cessation campaigns.
